Protein Domain : Nucleoside-specific channel-forming protein Tsx IPR003055

Type	Family
Description	The tsx gene of Escherichia coli encodes an outer membrane protein, Tsx, which constitutes the receptor for colicin K and Bacteriophage T6, and functions as a substrate-specific channel for nucleosides and deoxy- nucleosides []. The protein contains 294 amino acids, the first 22 of which are characteristic of a bacterial signal sequence peptide. The putative mature form of Tsx contains 272 residues with a calculated Mr of31418. The Tsx sequence shows an even distribution of charged residues and lacks extensive hydrophobic stretches []. Tsx shows no significant similarities to the channel-forming proteins OmpC, OmpF, PhoE and LamB from the E. coli outer membrane.
